I am looking for an IWB holster for a Glock 22. It would be for occasional carry but I'd want to be able to wear it for extended periods of time. One I have heard good things about is the Crossbreed Supertuck. Are there any specific issues with this holster for a Glock 22? Anything else I should check out? On the Crossbreed I have one more question - I also have a Kahr PM9. I believe Crossbreed holsters are designed so that the holster part can be replaced/interchanged. Would I be able to do this between a Glock 22 and the PM9? Or am I thinking about an entirely different holster? Thanks in advance.
